Sarah smiled grimly at the other woman. "Can't say I blame you," she offered kindly. She pulled a pair of tube socks out of the box, regarding them with a raised brow. Then, she offered them to the woman. "Here, put these on your feet. It won't do much, but it might help stave off some of the cold. If you've got a pair in your kit, layer them on top."
She regarded the remaining contents of the box critically. Matches were damp, but they could be dried out and possibly used later. Tic-Tacs wouldn't stave off hunger, but might give a bit of a sugar rush. The bottle of water and socks seemed to be the only things of real immediate use in the box. Why the journal was included, Sarah had no clue, unless it was to write down notes about the place. Which meant someone had put them here intentionally, not just rolled them out the back of a lorry or what have you. "I've got theories, none of them pleasant ones," she said in response to the woman's question. It wasn't as if Sarah hadn't found herself in odd situations before, after all.
She tucked the contents of the box into her pockets, then hauled herself to her feet, stretching her muscles carefully. She could feel lingering aches, and a bit of pain in her knees, but otherwise, she didn't feel too badly. She turned to the woman and smiled. "Sarah Jane Smith," she said, offering the woman her hand and a warm smile, despite the circumstances.
